Costco Wholesale CorpCostco doubled its Kirkland motor oil price and capped purchases as crude nears $100, squeezing its DIY value proposition.
Costco has doubled the price of its full-synthetic motor oil and begun rationing purchases as crude oil pushes toward $100 a barrel. A 10-quart case that cost roughly $30 now runs $57.99, with purchases capped at two units per member per week. U.S. diesel crossed $6 a gallon for the first time this week, and global oil inventories have drawn down more than 500 million barrels since the U.S.-Iran conflict began. The pressure on Costco is more intense because its signature Kirkland oil carries GM's Dexos1 Gen 3 certification, which requires manufacturers to pay GM separately per product and per unit sold, eroding the DIY savings case. It is not just Costco: Mobil 1 is also capped, at five units, with six quarts running $44. The International Energy Agency cut its 2026 global oil supply forecast to 102 million barrels a day in August and now projects a third-quarter deficit of 1.8 million barrels a day, while Chevron CEO Mike Wirth said last week that the buffers that had cushioned prior price spikes are now exhausted.
